Hi there, welcome to BYC!
Hardiness and friendliness was NOT my personal experience with Orpington... and nor do I suggest them. They are heavy bodied which means eat a bunch, too broody, genetically prone to fatty liver syndrome, not really human friendly or other flock member friendly.
Many birds are much better on paper than in person!
What I truly suggest is a variety that makes it easier to tell them apart at a glance, who is or isn't laying and tell their eggs apart, get a beautiful egg basket, identify which one needs help if they do, provide a lovely assortment of eye candy on pasture, etc... here are a couple comparison lists for several breeds...

I do suggest ordering from a hatchery or adding to a feed store order for spring... shipping can be rough depending on YOUR route, some chicks don't make it, feed stores absorb that before we get them usually. Also most breeders cannot sex their chicks unless it's an auto sexing breed or sex linked cross, so getting only females can be difficult if that the goal. Most hatcheries claim 90% accuracy sexing.
Or if you are getting them personally... buy from an NPIP breeder and protect yourself and property from any unknown illness that may not have presented yet at their current location.
Never bring birds from someone else pasture (or broody hatched) to your own. Learn this lesson the easy way by taking my advice on it.
Raising chicks will give you the friendliest if you have time to spend with them. The more the better. Ordering will also give you a chance to decide how you feel about Marek's vaccine... Marek's vaccinated birds NOT welcome here to HIDE the disease. One gene was identified that gives some immunity, and I will (TRY to) breed towards that. But for some folks, especially non breeders vaccinating is preferred.
My personal favorites have been Easter Eggers (not the boys), Rocks and French black copper Marans (including boys). Least favorite so far were the Oprington and Swedish Flower. I've raised hundreds of birds in dozens of breeds and no two were exactly the same. Line and breed matter, but each is an individual... just as we and our set ups are!
FWIW... I see an ad on my local (Oregon Coast) CL farm and garden section almost all the time... from Long Beach, Washington... offering Lavender Orps and goats. I also sell many of my birds on there and very serious about what I do including bio-security, despite not (yet) pursuing NPIP. So you can get quality animals... but discernment and being VERY familiar with what you are looking for are key. I can find the link if you'd like it.
My preferred hatchery of several I've ordered from is Meyers for overall quality and shipping success on
MY route.
Hope this is some good information that gives food for thought.
I know lots of folks will be happy to share their personal experience, and be along soon.
